Chui Pui Ling Page 45 The sequence diagram Create Instruction shows the classes interaction when an audio instruction is required by users. “CreateOneInstruction” shown as the name of a loop in the diagram is in fact a function in class Map but it is used as a loop name for simplicity. It is a fcuntion considers 3 coordinates at a time to produce one instruction and the detailed logic is shown as flowchart in Figure 22.
